For the past month or two I've been getting low virtual memory messages on my PC. I have ove 20gb free on my HD and 1.5GB of RAM(not sure if either is relevant), so does anyone know what my virtual memory setting should be?

Also, I've noticed that for the past two weeks, Firefix has been using huge amounts of memory, oftentimes hitting between 250 and 650KB. It used to run at around 100kb so this a drastic increase. Could that possibly be causing the virtual memory problems? And why is Firefox suddenly hogging so much of my pc's resources? I've ran countless virus scans and spyware scans with several different programs and everything keeps coming up clean.

Firefox has some serious issues with Memory leaks, and some javascript problems that leak memory too. but as always, your favourite browser allows for enoughcustomisation to work around it.

Open a new tab and enter about:config in the location bar, this should bring up a massive list of preferences, but be careful with it. Anyway, enter browser.cache.memory in the filter, and check that browser.cache.memory.enable is set to true, and check if you have browser.cache.memory.capacity, if not right click and choose new > integer, and name it browser.cache.memory.capacity

I have my capacity set to 16000, which stops firefox getting out of hand.

You might also want to check the values of browser.cache.disk.enable and browser.cache.disk.capacity too, and if you are still having troubles browser.sessionhistory.max_total_viewers tells firefox how many pages to keep in memory, try setting it to a number between 1 & 8, or 0 for 0 pages cached. -1 lets firefox choose itself.

Hope that can help you.

That's really useful to know, thank you for posting.

I was worried the Fox was becoming self-aware and on the verge of eating our dear Hockeynut.
